Application led March 16, 1914.

To @ZZ wiwm t may concern.'

Be it known that I, DAvID 0. RoYsTER, the United States, residing at Missouri, have invented a certain new and useful Improvement in Methods of and-Apparatus for Synchronously Making Motion-Pictures and Sound-Records, of which the following is a full, clear, and eX- will enable others the` art to which it appertains to make and use the same, reference being had to the accompanying drawings, in which- Figurel is-a diagrammatic. view with parts in section of an apparatus of my iinproved construction.

ig. 2 is a plan view of the apparatus with parts thereof in section. Fig. Sis a detail view of a valve which *surrounds vthe neck of the sound receiver of my improved apparatus.

1g. 4 is a detail view oi a valve such as --is utilized in the upper portion of the strucl YAY ture'inwhich the object to be photographed is located.

invention relates to a new and iinproved method of and sound recording device do iiot reach the latter f s are not synpictures when said sounds and pictures are later reproduced. Furtherd waves are insufficient to make a clear and strong record on the disk or cylinder of the recording' apparatus.

i further object of my invention is to Specification of Letters Patent.

l L Referring by Patented Feb. 4, 1919. `Serial N o. 824,894.

provide a transparent structure to be occup'ed by the photographed object, thereby electrically transmit-ted to the sound recordadjacent to and operated synchronously with the motion picture camera.v

lVith the above and other objects in view, my invention consists in certain novel features of construction and arrangement of parts hereinafter more fully described and claimed.

numerals to the accompanying drawings, 10 designates a structure preferably in the form of a small house, the front of which is open, and the side walls,

glass or analogous traiisparentmaterial, thus forming al chamber 16 in th structure.

Formed in the inner ceiling is a series of openings 17 whi h tube 2O in the ou'ter end located a. small suction fan 21.

Located at the upper end of tube 19 is a -telephonie receiver 22 and leading therefrom downwardly to a auxiliary ceiling l5 is a at its lower enc point beneath' the tube 23 provided with a mouth piece 24C.

and which air carrying uppervportion of K The sound recording device is Y' provided l with a reproducer 30.v4 Leading Jfroml the reproducer 30 to the transmitter .22 are conductors 3l which form acircuit between ysaid reproducer and transmitter, andlocated in this circuit is a suitable switch '32, a bat-.

tery 33, and induction coil34.

To synchronously make motion pictures and record sounds lby my improved method and with my improved apparatus, the switch 32 is closed, the camera 28 and recording device 29 are synchronously operated and blower 14 and suction fan 21 are operated.

The object of which records are to be made occupies the structure 10 and'all movements of said object will be recorded photographi- `cally upon the film. which is passin throu h the camera 28. At the same time t ie soun s made by the object will be carried upward through the structure by reasonvof the air blown thereinto by means of the blower 14,-

drawn upward into upward portion of the vstructure by suction fan 21.

The sounds thus concentrated enter the mouth piece 24, thence pass upward through 't'ube 23 to the receiver 22 and said sounds are telephonically transmitted to the reproducer 30 of the sound recording device.

The' concentration of thelsounds in the the lstructure can be readily regulated by manipulating the rotary valve 25 which surrounds the mouth piece-of the receiving tube 23, and also by manipulating the valves 18 which, when shifted' to partially open the Aapertures 17 permits a portion of the sound to enter the chamber 16 and to be carried through tubes 19 and 2O.`

An' apparatus of my improved construc- -tion is comparatively simple, can be easily operated, does not require artificial light, and motion p-ictures and absolute synchronism can be readily made at any distance from the object within the focal length of the camera.

t will be readily understood that minorform and construction of my improved appachanges in the size, of the various parts ratus can be made and substituted for those herein shown and described, without departing from the spirit of my invention, the scope of which is set forth in the appended claims.

It will be understood that where natural light isl not strong enough for the taking of pictures that the housing 10 Vcan be lighted articially.

I claim:

-operating a motion picture camera and a device, focusing the camera sound recording within. a hollow structure,

upon an obj ect cau'sing a current of air to'pass through said -transmitting said sounds from concentration to the sound waves is sound records oi away from said housing,

structure to carry the sounds made by the object toa common point, and electrically the sound recording device.

2. The hereindescribed method of synchronously y-inakingV motion pictures and sound records consisting 'in synchronously operating a motion picture camera and sound recording device, focusing the' camera upon an vobject within a housing located a distance from said camera, air pressure the sound waves produced within the'housing ata, common point, and elecggg the point of concentrating by trically transmitting Vthe sounds from the* point of concentration to the sound recording device.

3. In an apparatus of the class. described,

a hou'r'ing, a motion picture camera adapted to be focused upon an object within the housing, a sound recording device located a d istance from said housing, a. telephonie receiver located within the housing, means for concentrating sound the housing at or near the telephonie receiver, and electrical connections from said receiver to the reproducer of the recording device.
